Antibiotics can be classified in several ways: by their structure, which includes penicillins, fluoroquinolones, aminoglycosides, monobactams, and carbapenems; by their mode of action such as inhibiting cell wall synthesis, protein synthesis, DNA synthesis, RNA synthesis, myolic acid synthesis, or folic acid synthesis; and by their spectrum of activity such as being bacteriostatic, bactericidal, broad-spectrum, or narrow-spectrum. Some of the major classes of antibiotics classified by structure are penicillins like methicillin and ampicillin, fluoroquinolones like ciprofloxacin and levofloxacin, and aminoglycosides like gent
